Eclipse Android Dev Tool error R.java not generating

Development found my R.java file does not update, does not contain my latest resource information, I pulled him deleted, thought that after the deletion of eclipse will help me regenerate one, but eclipse did not do so ....

So my Android project didn't have a R.java file,

What should I do? I'm using Win7.

A related hint in the prompt box follows "" Doing Project->clean is what caused the problem for me. Cleaning deletes r.java...and for whatever reason the plugin was not regenerating the file. "

Processing methods

If your Android Engineer is clean, then he should regenerate one if not generated can take the following way;
Set up automatic compilation in Eclipse, update the R,java file every time it is modified, and if not, select Clean in the Eclipse Project menu. Clear the project and it should be regenerated.
